I just want to fit to a very simple equation, i.e. y = kx + b. Is that possible in MatLab? I need the slope, intercept and R-squared. In fitlm, mdl = Linear regression model: y ~ 1 + x1 + x2 + x3 Does it mean it is fitted as y = 1 + x1 + x2 + x3? Why it is not as the form of y = kx + b ?

Linear Regression Prepare Data. To begin fitting a regression, put your data into a form that fitting functions expect. All regression techniques begin with input data in an array X and response data in a separate vector y, or input data in a table or dataset array tbl and response data as a column in tbl.

MATLAB Features: data analysis Command Action polyfit(x,y,N) finds linear, least-squares coefficients for polynomial This MATLAB function returns a linear regression model fit to variables in the table or dataset array tbl. LinearModel is a fitted linear regression model object. A regression model describes the relationship between a response and predictors. The linearity in a linear regression model refers to the linearity of the predictor coefficients.

There are two sets of data: one for O2 and one for Heat. I made a linear regression in the plot of those two data sets which gives me an equation of the form O2 = a*Heat +b. So now I need to find the confidance interval of a. That for I need to find the standard deviation of a which I somehow just can't find out how to get it.

L contains an MSE for each regularization strength in Mdl. L = loss (Mdl,Tbl,ResponseVarName) returns the MSE for the predictor data in Tbl and the true responses in Tbl.ResponseVarName.

Linear Regression Prepare Data. To begin fitting a regression, put your data into a form that fitting functions expect. All regression techniques begin with input data in an array X and response data in a separate vector y, or input data in a table or dataset array tbl and response data as a column in tbl. Each row of the input data represents one observation.
